Agreed, but...

Now done_help is not initialized, but we read from it before assigning
it. And I think there is no need for was_alias to go outside the loop,
right?

Dropping the initialization of was_alias is fine, since we always assign
to it before reading. That becomes more obvious if we leave it in the
loop, and we can even assign in its declaration.
So all together, like:
